' Thisinventionrelates to improvementsin railway motor cars and vmore vparticularlyto an improved deck arrangementxand `superstructureffor lrailway section 'and inspection Y x35 cars.

*The 'object of this' invention is the ycreation o'f 'a deck `structure, for Aa car jof the described ola'ss'which' 'willemb'ody the feature of protecting thefeet and 'clothing of the occupants i lo olfth'e car, 'from the wheels and other moving parte offtlrefyehicle. f l

further 'Objectis to provide a deck strucf ture which will afford much more than the usualde'cl; `area 'provided 'on railway motor 15 cars', and vwhich will serverthe'purpose usually ,accomplished by the yuse Voffsepaiate wheel guardsor t'o'e-'boar'dafand at the same timey will provide ja secure carrying place for tools fand ,working equipment. p

,"furfther object of 'his yinvention is the provisionlfof a 'railway motor Acar 'of the kind used bybridge maintenance gangs and section "men of railway companies, -which car is llight Ain weight, of simple construction,

manufacture.v v f v*Further objects 'andadvanta'ges of 'my 1nf vention willappear from the drawing and the followingdescription thereof.

' lthoug'h my invention consists largely v1n the construction and arrangement of parts lhereinafter described and particularly lpoin'ted out Iin 'the claims, yet I -do 4not limit my [invention to theprecise form =or construction ofparts shown or the several parts thereof, inasmuch as various alterations maybe made without changing the scopeof my invention.

`Referri1ig-to the drawings, Fig. l shows -a front elevation*inperspective of a .railway motor oareinbodyi-ngmy invention; Fig. '2 isa view, illustrating the declr arrangement; V3 is agpersp'ective view of a y'slightly modified formk of motor car, showing additional details of lthe deck and seat construction; Fig.' 4 and rare side and` end elevations, respectively, of a preferred seat sup-y porting '-member.'` l e Referring byk umerals to the drawings, 5 show'sfa'napprovedlocation and arrangement ojfframe side members. The 'frame also insafe to operateand Asimple and economical toy cludes transverse end members 6, the members 5 land 6 being preferably of pressed steel construction, V and riveted together. These frame ymembers ,may serve as supports for an engine with related transmission equipment. In lieu of, or in conjunction with the members 6, a tubular end member 6v may be disposed atone or both en'd's of the car to strengthen the frame, and serve as lifting handles and bumpers. The members 5 and 6, together with tubular members 6", when used, constitute thefunderframe of the vehicle. .It will be understood that members 6 are not absolutely necessary to the described construction, -but are preferred asa convenience for :the purpose described. Preferably vtransversely :to :and labove the .members 5, ,are located one 'or more cross-sills 8. These crosssills may `be formed of wood or other suitable material and bolted, `clamped or otherwise ixedly mounted abovethe frame side members 5. vI :greatly prefer that cross-sills 8 shalfl project at least as far as, and preferably beyond the outsideof the wheels l5, so 'that the Asills andr decking, described below, willy serve fas a wheel guard, vvor toe-guard, as well as a car-deck. rlhe prevailing practice is to form 4the wheel guards as separate attachments, disposed outwardly from, and above the l'deck vhereinafter described. By employing the raised cross-sills 8, extending outwardly beyond the wheels, I lhave succeeded 'in-combining the decks and wheel guards,fand in increasing the available deck width. l have illustrated in Fig. l, some of the crosssills' 8 as extending only a short distance across/each sideof the motor carframe. Obviously,"[ may 'extend all of the sills '8 completely 'across the frame/of the car `by locating the engi-ne or primemover 7 slightly above or ybelow theposition shown in Fig. l, in which some `of the sills 8 Vare shown as being fragmentary, merely because of the particulafry position which the eng-ine occupies in the example shown. prefer, when possible, to use two or .more such sills, each of which shall eXtendfrom one :side o-f the carclear through to the other. Preferably immediately above sills 8 transverse' thereto land supported thereby, are the combined deck members and ywheel guards and 10 on the right and left sides of the car, respectively. These decks serve as a licor forthe car, as guards or toeboards over the wheels, and as a space for carrying tools and equipment. 'Ihese deck members karen-preferably provided ,with

guards or raves near the sides and ends thereof, so as to provide an enclosure for the tools and track equipment ordinarily carried by cars ofthissort.'V The deck raves arerindi- 4 cated at 11." 'Ilie `deck structures' 9 andjl() are, by preference, slightly inclined-,to the horizontal, i. e., slightly inclined toward the center of the car. Vhereafcontinnous deck structure is employed, as iii Fig. 3, the center i will suffice for a support for one end of the seat 12. The opposite end of the car ispreferably'provided with a Vgrab ironie, which may .bei riveted to the Irear .transverse end member 6, or secured tothe seat 12, as shown. The rear end'of seat 12 isjby preference supportedfcentrally, at one point, by a rigid support 16, for example a U shaped channel'mem-v ber riveted to the transverse end member 6. The'seat12 is built up on a `pair or more'of longitudinal seat sills 18, and' transverse Yseat sills 19. The support'16 may be suitably se- `cured tothe rear sill 19, as yby riveting.V The seat sills 18 and 19 are of suiicient strength to withstand usual yloads incident to their use, Without requiring the usual intermediate and corner support posts.A This arrangement provides an unusualamount'of unobstructed deckspace, and'renders the entiredeck'space easily accessibleand available for larger tools and othery equipment of' substantial size. n' -Y At 15 I have indicated the wheels of the car. These'may bel of the usual' construction. and, together withk the l frame members 5 and 6 and the engine 7, constitute'the runninggear ofthecar.`

The advantages of the construction "described above `are thought to be apparent to those familiar with theV manufacture and use Vofrailwayequipment of this'sort. The prevailing practice isto provide a deck structure wliich'assume a lvarietyof forms and which usually consist of.separate pieces of sheet metal or a strip of wood extendinglaterally i fromftheframe and secured thereto by means of bracketsl orY iaiiiglebars.V It may befseen that the construction"I herein described aflfords adequate protection for the occupants of the car from the wheels and other moving partsy of the car Vwithout the use of accessories, guards, or attachments, this protection being afforded by the deck structure. The feature. of iiiclining the wide deck .toward theceiiter andv 4of employing the transverse cross-sills 8 and the decking 9fand 10 for the dual purpose of affording a greater deck area and serving the function of the present toe-v boards, wi-ll tend toward economy in manufacture, simplicity in construction and great- Ier utility of the vehicle. ,IlVliatI claimis.:
